Add k6 test for fungible token lifecycle

[nickeynikolovv]

This PR adds a k6 test that covers the lifecycle of a fungible token. The contract function that

1. Create token
2. Associate token
3. GrantKyC
4. transfer from treasury to acc1
5. freeze / unfreeze
6. transfer from acc1 to acc2
7. wipe token amount from an account
8. pause / unpause

The detailed contract function is:

function tokenLifecycle(address acc1, address acc2, address treasury) public payable {
        IHederaTokenService.TokenKey[] memory keys = new IHederaTokenService.TokenKey[](5);
        keys[0] = getSingleKey(KeyType.ADMIN, KeyType.PAUSE, KeyValueType.INHERIT_ACCOUNT_KEY, bytes(""));
        keys[1] = getSingleKey(KeyType.KYC, KeyValueType.INHERIT_ACCOUNT_KEY, bytes(""));
        keys[2] = getSingleKey(KeyType.FREEZE, KeyValueType.INHERIT_ACCOUNT_KEY, bytes(""));
        keys[3] = getSingleKey(KeyType.WIPE, KeyValueType.INHERIT_ACCOUNT_KEY, bytes(""));
        keys[4] = getSingleKey(KeyType.SUPPLY, KeyValueType.INHERIT_ACCOUNT_KEY, bytes(""));
        IHederaTokenService.Expiry memory expiry = IHederaTokenService.Expiry(0, treasury, 8000000);
        IHederaTokenService.HederaToken memory token = IHederaTokenService.HederaToken("TKN", "TK", treasury, "memo", true, 1000000, false, keys, expiry);
        (int code, address tokenAddr) = HederaTokenService.createFungibleToken(token, 1000000, 8);
        require(code == HederaResponseCodes.SUCCESS, "Token creation failed");

        require(HederaTokenService.associateToken(acc1, tokenAddr) == 22, "Token Associate of failed for acc1");
        require(HederaTokenService.associateToken(acc2, tokenAddr) == 22, "Token Associate failed for acc1");
        require(HederaTokenService.grantTokenKyc(tokenAddr, acc1) == 22, "GrantKyc failed for acc1");
        require(HederaTokenService.grantTokenKyc(tokenAddr, acc2) == 22, "GrantKyC failed for acc2");
        require(HederaTokenService.transferToken(tokenAddr, treasury, acc1, 100) == 22, "Transfer token failed from treasury to acc1");
        require(HederaTokenService.freezeToken(tokenAddr, acc1) == 22, "Freeze token failed for acc1");
        require(HederaTokenService.unfreezeToken(tokenAddr, acc1) == 22, "Unfreeze token failed for acc1");
        require(HederaTokenService.transferToken(tokenAddr, acc1, acc2, 50) == 22, "Transfer token failed from acc1 to acc2");
        require(HederaTokenService.wipeTokenAccount(tokenAddr, acc2, 10) == 22, "Wipe token failed for acc2");
        require(HederaTokenService.pauseToken(tokenAddr) == 22, "Pause token failed");
        require(HederaTokenService.unpauseToken(tokenAddr) == 22, "Unpause token failed");
    }

Notes for reviewer:
Changes in the deploy branch for mainnet config will be done in a separate PR.

There are following complex scenarios that will be added and the contract will be updated in stages. Therefore to avoid new contract deploy on mainnet on each PR those tests will be disabled from the flag RUN_COMPLEX_TESTS until the contract is fully ready and deployed once at the end.

We need to also check the solidity file in somewhere and link to it in the k6 README.

From my previous comment:

and link to it in the k6 README.

We should have a section in the README that describes and links to the source of various k6 tests so that we can reproduce k6 data easily. It doesn't have to be for every existing test but at least the one you added in this PR.
